Hello, my name is Kent I play tennis on my high school varsity team. Recently my teammates and I have been breaking a lot of strings. This has cost my teammates and I a lot of money. I am very good at tennis, I play number 1 Doubles, and Number 1 singles on occasion. I have come up with an idea for all of the tennis players in my area. My plan is to buy a stringing machine and string rackets at low prices, because cost is an issue here. I am in need of tennis stringing machine that is not drop weight system. I am looking for anything better than that that can give me a constant tension. Does anyone know of any stringing machines that has a price of $500.00, at I price I can afford? I would prefer not to have Silent Partner, or Egnas. Also, does anyone know where I can get used stringing machines from? PS: What do you think of a used EKTELON MODEL H TENNIS RACQUET STRINGING MACHINE? Would this be a good choice?
